Hi,
the command doesn't return because your PGs are inactive. It looks
like you're trying to use the default replicated_rule but it can't
find a suitable placement. What does your 'ceph osd tree' look like?
And also paste your ruleset ('ceph osd crush rule dump
replicated_rule').
Regarding OSD management you could have simply let cephadm choose all
available disks for you [1]:
ceph orch device ls
ceph orch apply osd --all-available-devices
Or create a service spec yaml file and simply run 'ceph orch apply -i
osd-specs.yaml' once to deploy all OSDs at once on all target nodes
from that yaml file.

Zitat von Renato Callado Borges <renato.callado@xxxxxxxxxxxx>:
Dear all,
I am deploying a Ceph system for the first time.
I have 3 servers where I intend to install 1 manager, 1 mon and 12
OSDs in each.
Since they are used in production already, I selected a single
machine to begin deployment, but got stuck when creating rbd pools.
The host OS is Centos 7, and cephadm allowed me to install Octopus.
These are the commands I have issued so far:
./cephadm add-repo --release octopus
./cephadm install ceph-common
cephadm bootstrap --mon-ip "X.X.X.X" # edited for privacy, real IP used.
ceph orch daemon add osd darkside2:/dev/sdb
This latest add command was repeated 12 times, once for each block
device to be added to Ceph storage.
ceph osd pool create lgcmUnsafe 128 128
Until here, everything seemed fine, no error messages on journalctl
or on /var/log/ceph/cephadm.log. I have run ceph status after each
command and the output seemed consistent.
This command, though, gets stuck forever, with no error or warning
message anywhere:
rbd pool init lgcmUnsafe
I have canceled the command with ctrl+c and issued ceph status. This
is the output:
cluster:
id: 1902a026-496d-11ed-b43e-08c0eb320ec2
health: HEALTH_WARN
Reduced data availability: 128 pgs inactive
Degraded data redundancy: 128 pgs undersized
services:
mon: 1 daemons, quorum darkside2 (age 19h)
mgr: darkside2.umccvh(active, since 19h)
osd: 12 osds: 12 up (since 19h), 12 in (since 4d); 1 remapped pgs
data:
pools: 2 pools, 129 pgs
objects: 13 objects, 0 B
usage: 12 GiB used, 175 TiB / 175 TiB avail
pgs: 99.225% pgs not active
26/39 objects misplaced (66.667%)
128 undersized+peered
1 active+clean+remapped
Could someone more knowledgeable help me debug this, please? Thanks
in advance!
Cordially,
Renata.
